Penelitian yang dilakukan merupakan jenis penelitian dan pengembangan atau Research and Development (R&D) menggunakan metode ADDIE (Analysis, Design, Development and Implementation, Evaluation). menggunakan 5 orang validator ahli, yaitu; ahli materi, ahli media dan 3 ahli praktisi guru IPA. uji coba lapangan dilakukan disekolah SMPN 8 Tarakan, uji coba lapangan awal menggunakan siswa kelas VIII-4 sebanyak 9 orang dan uji coba lapangan utama menggunakan siswa kelas VIII-6 sebanyak 23 orang. Hasil validasi ahli materi sebesar 75% dengan kategori baik, ahli media sebesar 82,5 % dengan kategori sangat baik, rata-rata hasil validasi praktisi guru IPA 1, 2, dan 3 sebesar 82,22 % dengan kategori sangat baik. Hasil angket respon siswa uji coba lapangan awal sebesar 81,48 % dengan kategori sangat baik, dan hasil angket respon siswa uji coba lapangan utama sebesar 84,28 % dengan kategori sangat baik. Sehingga dapat disimpulkan bahwa alat peraga yang dikembangkan tervalidasi sangat baik dan layak digunakan.
